3yr old sleeping on floor in doorway but wont sleep on bed

Did it start recently?

Any changes in bed/family/life/routine?

My son did that. Put a comforter down for him to sleep on. He'll grow out of/tired of this. They get weird ideas sometimes and this one isn't a biggie.

Well he's slwepixg. When I was young 4,, I used to sleep under by bròther's crib. I would grab my pillow and blanket and sleep there. I was happy I slept godo so my parents let me.

Sounds like he's made a link to something bad in bed like nightmares or something else.
